Preventing an air embolism while diving

The following advice can help reduce your risk of developing an air or gas embolism when diving. Limit the depth and duration of your dives. Come up to the surface slowly and always perform safety stops to allow any air in your tissues and blood vessels to escape safely. Use a dive computer or dive tables, and don't dive again if you have broken these rules until you have had a suitable time at the surface. Don't dive with a cold, cough or chest infection. Avoid rigorous exercise before, during and after a dive. Make sure you're well hydrated before diving. If planning several dives, leave adequate surface intervals between dives to allow the nitrogen to leave your body. After diving, wait for 24 hours before flying or going to a higher altitude. If in doubt, contact a dive professional or doctor, who can provide further advice.
